Your Guide to 40 of the Most Prominent Internet Slang Terms

Hey fam! Strap in, bc we’re about to go over some Internet slang terms that, ngl, are pretty fire.

Okay, sorry. You can stop cringing now, I’m done. If you were struggling through that last bit, though, you’re probably not alone. There are countless Internet slang terms out there which, if you’re above 25 (or if you’re just not chronically online), you may not know. That’s why on this page, I’ll be defining 40 of the most ubiquitous online slang terms out there.

Of course, these 40 terms are just the tip of the iceberg. The reality is, there are more Internet phrases and acronyms out there than anyone could possibly count, especially when you consider that many of those terms aren’t limited to the Internet. Still, these 40 terms are a good start.

So, if you’re desperate for help understanding “the youth,” keep reading to learn more. And if you ARE “the youth”… feel free to sit back and watch me proceed to ruin every single one of these terms for you by trying to explain them.

This list is divided into two sections. Many Internet slang terms are acronyms, so we’ll start by covering 20 Internet acronyms. The second half of this list consists of 20 non-acronym terms, which I’ll refer to as Internet phrases. For each term, I’ll give the meaning, as well as an example of the term in context.

Now that you know all of these Internet slang terms, you may be eager to start using them. But keep in mind that not everyone uses all of these terms. (I’m technically part of Gen Z, but I’ve never once used the phrase “no cap.”) Also, slang changes quickly, so there’s no telling how long these acronyms and phrases will remain in use.

All that to say, don’t feel like you should be throwing out these terms in random conversations — not unless your goal is to embarrass any teens and twenty-somethings in the vicinity. But at the very least, this list should help you understand those terms when other people use them.

Anyway, that wraps up this blog post. If you’re just a regular adult desperate to understand the youth, I hope you found this helpful. But maybe you’re someone trying to learn these terms so that you can better communicate with a young audience in your online marketing.

If that’s the case, I can’t say I recommend trying to use most of this online slang in your marketing — that’ll probably just come off as (to use our new vocab) cringey. But there are definitely other ways you can improve your digital marketing, and at WebFX, we know what it takes to do that.
